Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on your description, it appears that this could be a skin infection / irritation. Without pictures and without examining Zoey, it is difficult to say for sure. The large swellings under the armpits could be enlarged lymph nodes due to the bacterial skin infection. I would recommend having a veterinarian take a look at this so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
